Two lines of open pollinated canola have been engineered for tolerance to the herbicide glufosinate ammonium. Five lines of canola have been engineered for use in hybrid seed production by the addition of genes controlling pollen production in addition to the gene conferring tolerance to glufosinate-ammonium. In North America, the canola is known commercially as Liberty Link open pollinated and InVigor hybrid canola. These genetically modified canola lines are currently not grown in either Australia or New Zealand but oil from these lines may be present in imported processed foods. Issues addressed during assessment (i) Safety evaluation Oil derived from the seeds of glufosinate-ammonium tolerant and pollination controlled canola lines Topas 19/2, T45, Ms1, Ms8, Rf1, Rf2 and Rf3 has been evaluated according to the safety assessment guidelines prepared by ANZFA. The assessment considered the following issues: (1) the nature of the genetic modifications; (2) general safety issues such as novel protein expression and the potential for transfer of antibiotic resistance genes to microorganisms in the human digestive tract; (3) toxicological issues; and (4) nutritional issues. On the basis of the available information, it is concluded that oil derived from these genetically modified canola lines is as safe and wholesome as oil from other commercial canola varieties. A detailed food safety report on these foods has been prepared. (ii) Labelling information for consumers Under the current Standard A18, which remains in effect until 7 December 2001, oil derived from glufosinate-ammonium and pollination controlled canola lines Topas 19/2, T45, Ms1, Ms8, Rf1, Rf2 and Rf3 does not require labelling as it is regarded as substantially equivalent to oil from non-genetically modified canola varieties. When the amended Standard comes into effect on 7 December 2001, food products containing canola oil derived from any of these genetically modified lines will require labelling if it can be shown that novel DNA and/or protein is present in the final food. (iii) Public consultation ANZFA undertook two rounds of public consultation in relation to this application and a total of 68 submissions were received overall – 45 submissions in the first round and 23 submissions in the second round. The majority of submissions were not supportive. Those opposing the application did so primarily on the basis that they perceive GM food to be unsafe or environmentally unsound. The food safety concerns raised in submissions have been addressed by the safety assessment report. 3 Conclusions § There are no public health and safety concerns associated with the genes introduced into glufosinate-ammonium tolerant and pollination controlled canola lines Topas 19/2, T45, Ms1, Ms8, Rf1, Rf2 and Rf3. § Oil derived from genetically modified canola lines Topas 19/2, T45, Ms1, Ms8, Rf1, Rf2 and Rf3 is as safe and wholesome as that from other commercially available canola varieties. § From 7 December 2001, food products containing oil from genetically modified (glufosinate-ammonium tolerant and pollination controlled) canola will require labelling if it can be shown that novel DNA and/or protein is present in the final food. § The proposed amendment to the Food Standards Code is consistent with the section 10 objectives of the Australia New Zealand Food Authority Act 1991 and the regulatory impact assessment. 4 1. BACKGROUND TO THE APPLICATION Canola (Brassica napus) has been genetically engineered for tolerance to the herbicide glufosinate-ammonium and for the production of higher yielding fertile hybrids. In this application, seven glufosinate-ammonium tolerant canola lines (Topas 19/2, T45, Ms1, Ms8, Rf1, Rf2 and Rf3) have been generated. Two of these, Topas 19/2 and T45, are open pollinated canola lines known commercially as LibertyLink canola. The Ms and Rf lines are pollination-controlled parental breeding lines for use in hybrid production and are known commercially as InVigor hybrid canola. All seven lines are tolerant to the broad-spectrum herbicide glufosinate-ammonium, the active constituent of the proprietary herbicides Basta, Finale, Buster, Harvest and Liberty. Tolerance to glufosinate-ammonium (also known as phosphinothricin) is conferred by the transfer of one of two bacterial genes – either bar or pat. These genes produce the enzyme phosphinothricin acetyl transferase (PAT), which breaks down phosphinothricin into an inactive form, allowing the modified plants to tolerate application of the herbicide. The bar gene is derived from the soil bacterium Streptomyces hygroscopicus and the pat gene is derived from a closely related species Streptomyces viridochromogenes. In addition to bar or pat, the male sterile (Ms) lines contain the barnase gene derived from the bacterium Bacillus amyloliquefaciens. The presence of this gene in the plant results in abnormal development of the parts of the flower that produce pollen. The fertility restorer (Rf) lines express the barstar gene (derived from the same bacterial species), which counteracts the effects of the barnase. The presence of the barstar gene has no direct effect on the plants and is only evident when an Rf line is crossed with one of the Ms lines to produce hybrid plants in which both genes are expressed at the same stage in development. These plants exhibit greater vigour than either of the parental lines and are fully fertile yielding greater amounts of seed. Canola seed, a genetic variation of rape-seed, was first developed in Canada through traditional plant breeding techniques that specifically aimed to maximise nutritional value. The seeds are crushed to obtain canola oil for human consumption, while the remainder is processed into canola meal, which is used as a high-protein livestock feed. Canola oil contains the lowest level of saturated fatty acids of any vegetable oil, and is used in table spreads and for cooking purposes. At present, the key markets for canola production are Canada and the US, however, because of export food markets, oil produced from genetically modified canola may enter the Australian and New Zealand market in imported processed food products. The direct benefits of the new genetic modifications outlined in this application are likely to accrue mainly to the primary producer by way of increased choice of commercially available, higher yielding varieties of canola. More general benefits may also flow to the community as a result of reduced primary production costs. 2. PUBLIC CONSULTATION ANZFA completed an Initial Assessment (formerly referred to as the Preliminary Assessment Report) upon receipt of the application and invited submissions from the public between 3 November 1999 and 12 January 2000. A total of 45 submissions were subsequently received and a summary of these is included in this report at Attachment

    Shankar et al. Microb Cell Fact (2021) 20:171 https://doi.org/10.1186/s12934-021-01642-y Microbial Cell Factories RESEARCH Open Access Recombinant expression of Barnase in Escherichia coli and its application in plasmid purifcation Ram Shankar1* , Nina Schäfer1, Marco Schmeer1, Joe Max Risse2, Karl Friehs2 and Martin Schleef1,2,3* Abstract Background: The use of bovine-origin ribonucleases has been part of the standard protocol for plasmid DNA purif- cation. As the feld of gene therapy now enters the clinical stage, such enzymes need to be phased out or alternative purifcation protocols need to be developed to ensure product safety and regulatory compliance. The recombinant expression of bacterial RNase is fraught with toxicity problems making it a challenging enzyme to express. The current study describes a plasmid construct that allowed expression of barnase in Escherichia coli under co-expression of its native inhibitor barstar. Results: The pure enzyme without the inhibitor barstar was exported to the extracellular space through the peri- plasm and then purifed from the cell-free supernatant. Cation exchange chromatography was employed as a primary purifcation step. This was followed by hydrophobic interaction chromatography which resulted in a concentrated fraction of active enzyme. Although current levels of volumetric activity achieved are quite meagre (4 Kunitz units 1 mL− ), in principle its application to plasmid DNA purifcation could be proved. Currently, this is capable of processing small amounts (13 g) of bacterial biomass for plasmid production. Conclusions: The current work focusses on the downstream purifcation strategies for a recombinant RNase and sets a framework for higher scale production if specifc productivity is increased by optimal hosts and/or re-engineered plasmids.

The basic functions of an antibody can be spatially differentiated and attributed to various struc- tural domains of a molecule. Therefore, each of them may be an object for engineering with the aim of using a definite antibody function. In this sense, the potential of antibodies is unique. In this article, recent achieve- ments and current problems of antibody engineering are briefly reviewed. The main attention is focused on a molecular constructor that allows for obtaining, with the help of a versatile barnase–barstar module, mono- and multivalent miniantibodies and their derivatives with outlined properties.
